Harmony 890 just went dead. Nothing. Nada. Not

Not worth repairing, contact harmony and they will give you a coupon for 50% off a new remote. The 900 replaced the 890, although I prefer the 890 the screen is a lot better on the 900.

This issue has been identified in a couple of other forums. I read that the display LCD was dead and that it needed replacing. I ordered a new screen on ebay, just search on LCD SCREEN FOR Logitech Harmony 880 ,890 REMOTECONTROL the part number is 141192-0000 (I think) it was under $27 and was shipped promptly. Easy fix. Two screws and six tabs to pry apart carefully to remove the back. Two screws to remove the motherboard. Carefully remove the daughterboard (be careful the motion sensor on mine was glued and the top popped off. It was a bear finding the mini gold ball that is inside the sensor after it fell on the floor. The LCD connector's dark piece pulls straight up and then slide out the flat cable.
Easy, quick fix.

The display will likely have to be replaced. You will have to contact Logitech to see if it's worth the repair cost.
